Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005928, here are decompositions:
- 17 + 1005911 = 1005928
- 101 + 1005827 = 1005928
- 107 + 1005821 = 1005928
- 167 + 1005761 = 1005928
- 227 + 1005701 = 1005928
- 251 + 1005677 = 1005928
- 281 + 1005647 = 1005928
- 311 + 1005617 = 1005928
Showing the first eight; more decompositions exist.
